The stone ascent

The Sage continues: "If you gently separate the earth from the water, the subtle from the hard, the Stone ascends from earth to heaven, and again descends from heaven to earth, and receives its virtue from above and from below. By this process you obtain the glory and brightness of the whole world. With it you can put to flight poverty, disease, and weariness; for it overcomes the subtle mercury, and penetrates all hard and firm bodies."

An alchemic stone

So, too, the matter of the Stone shews most beautiful colours in the production of its flowers. The comparison, also, is apt, because a certain matter rises out of the philosophical earth, as if it were a thicket of branches and sprouts: like a sponge growing on the earth. They say, therefore, that the fruit of their tree tends towards heaven. So, then, they put forth that the whole thing hinged upon natural vegetables, though not as to its matter, because their stone contains within itself a body, soul, and spirit, as vegetables do.
